A core outcome set in subarachnoid haemorrhage research

A core outcome set in subarachnoid research is both necessary and attainable. Our systematic review demonstrated substantial heterogeneity in the outcome measures employed in subarachnoid haemorrhage research. The development of a specific core outcome set will engage relevant stakeholders including patients, families, researchers, clinicians, allied health workers and policy-makers and identify which outcome measures should be prioritized during research. This specific core outcome set will aim to achieve consensus on how and when to measure these outcomes.
